+To prevent an MMF client with multiple controllers running out of chunks, all
+controllers for the same client are made to use the same heap.
+  
+This class controls that shared heap.
+  
+The iRefCount tracks the number of controllers using the heap.
+  
+When the client requests a pointer to the heap - RegisterHeap() - it is 
+assumed that a controller will be created using it, so the refcount
+is automatically incremented. When the controller terminates, the client 
+unregisters - ReleaseHeap() - and the ref count is decreased.
+When the refcount is zero (no controller threads left) the client deletes 
+this class.
